I own a shotgun (for fun) and am hardly anti firearm in any way shape or form but I still find the protection argument pretty hilarious. If a person owns a gun for protection he is potentially willing to take a life to protect himself and his loved ones but if he isn't CPR certified (or AED trained) he can't save his loved ones (or a bystander) from cardiac arrest or help if someone stops breathing. If you live in the country it becomes even more important as help is even further away.

That idea that people know more about fire arm ownership than CPR is pretty terrifying.
